"Survive on Mars is a multiplayer survival game in development for Microsoft Windows, OS X, and Linux. In the game, players have the task to survive on the "Red Planet" by crafting items using the materials they gather.
They can explore the world to get resources, they can plant and grow food, make water, create rovers, drones.
The nights on the "Red Planet" are cold, so.. stay in your base.
The crafting system is simple, you need only resources and a blueprint to craft an item.
The building in the game is simple and easy. You can place a building part anywhere or if you want to unite a part with another, they will link together automatically.
You need to have a laser builder to build something.
The game will pick a random time and you can see a meteorite every 30 or 60 minutes. Find craters and get the resources from it.
The helmet will protect you 'only' when you have Oxygen in your tank... if not, you will die. Outside you will need to use it, but when you are inside and the base is locked (with walls and doors) and have a oxygen generator, you can remove it and you can breath the oxygen from the base.
On a phone you will see the health, the oxygen from the tank, when you need to eat and when you need to drink.
You can grow food and make water in your base.
Each player have a spacecraft. The player are spawned random on the map and they can't move the spacecraft. So, a spacecraft is the temporary home of the player.
You can buy new items or get a resupply mission with credits.
With a laser scanner you can scan rocks to see what they contains."
